INVENTOR (some W. ALLAN W {IZTORNEY Patented Apr. 24, 1951 UNITED STATES PATENT OFFICE 25 Claims.

This invention relates to calculating machines of all types including accounting machines and adding machines, and this application is a continuation in part of my co-pending application Serial No. 451,813 filed July 21, 1942, now abandoned, for Control Plate and Control Means for Bookkeeping Machine.

ord produced by the machine will include the identifying characters, such as a name and address, together with the figure transferred from the storing device to the machine, such as an old balance, the figures entering into the calculation, and the new balance which is set in the storing device.

My invention is widely applicable to different types of calculating machines and is useful in many different fields. However, for purposes of illustration, I have disclosed my invention as embodied in a device particularly useful in bank accounting, and I have chosen as the machine to which my mechanism is to be applied the bank accounting machine disclosed in the patent to Christian No. 2,038,717, issued April 28, 1936. I

desire to have the disclosure of that patent, as well as all of the patents referred to therein, particularly the patent to Ellis No. 1,203,863, issued November 7, 1916, to be considered as part of this disclosure and, for details of the accounting machine itself, reference is to be had to said patents.

OPERATION OF THE MACHINE OF THE CHRISTIAN PATENT In the following disclosure when reference is made to parts found in the machine of said Christian patent, the same reference numeral will be employed as that applied'to the. part in the patent. Figures referred to are figures in the drawings of this disclosure unless otherwise stated. Referring to Figure 1, the keyboard of the machine comprises a plurality of keys I 2|,

each of which is provided with a pin I22 (Figures 4 and 5) which in the depressed position of the key serves as a stop for controlling the rearward movement of the rack SI by means shown in Figure 3 of the above-cited patent to Christian, which rack has a pin and slot connection 89, 90 with an arm 85 which is connected through a link 91 with the type actuator 98. The paper tapes are conducted by a guide 5I8 to pass over a platen 05. One of the characteristics of said Christian patent is that old balances, checks. deposits, and new balances can be printed in a vertical column on a paper tape which is fed vertically. An example of the record which can be produced by this machine is shown in Figures 42 and 46 of said Christian patent.

As disclosed in said Christian patent, the rack 9i (Fig. 6) has cooperating therewith four totalizers 508 which ar numbered 1 to 4. By means of the racks 9! values set in the keyboard can be entered into the No. 1 totalizer additively or subtractively depending on whether th entry is a debit or a credit. The No. 2 totalizer accumulates new balances, the No. 3 totalizer accumulates the total amount of checks, and the No. 4 totalizer accumulates the total amount of deposits.

As explained in said Christian patent, at the beginning of the day the operator sets the date in the device 400 (Fig. 1) so that this date will be printed on the record. In posting an individual account the bookkeeper looks up the old balance which he sets in the keyboard I2I and then depresses the sub-total key 392 and the motor bar 50. This causes the old registered in the No. l totalizer only; this figure is not registered in the other three totalizers. The operator then posts the checks by setting the amount of the check in the keyboard I2 I, depressing the check key I44 and the motor bar This causes the amount of the check to be subtract-ed from the No. l totalizer and added in the No. 3 totalizer. He posts the deposits by entering the amount in the keyboard I2i, depressing the deposit key I32 and the motor bar This causes the amount of the deposit to be additively registered in the No. l totalizer and in the No. 4 totalizer. After posting the checks and deposits of the individual account, the operator depresses the balance key 282 and the motor bar This causes the No. l totalizer to be cleared and the total standing therein to be printed as the new balance. The amount of the balance is registered in the No. 2 totalizer. In the case of an overdraft the complement of the amount is registered in the No. l totalizer and, in order to print the overdraft as a true figure, means are provided which are under the control of the overdraft key .5.

INVENTION IN GENERAL As will presently appear from the following disclosure, my invention eliminates the use of printed records of the previous balance in each account, reduces the amount of time and work required to post accounts, eliminates the possibility of human error in picking up old balances, and eliminates the possibility of the bookkeeper altering or in any way tampering with the account balance.

In accordance with my invention I provide a mechanical device for each account in which the balance or the account is represented by an adjustable means which is locked when the device is removed from the machine. When an account is to be posted, the storing device containing the balance to be additively a Ii) balance figure of that account is placed in the machine wherein means is provided for automatically picking up the old balance from the storing device and transferring it to the calculating mechanism of the machine.

Once the old balance has been automatically picked up, the machine of the Christian patent is operated in the usual manner to post the account and, at the conclusion of the posting operation, means is provided for setting the new balance in the storing device. In order to follow the se quence of posting operations described above, I shall first describe one of the storing devices and explain how the total stored therein is automatically picked up by the machine and then show how a new balance is stored in the storing device.

STORING DEVICE The storing device I000 (Fig. 8) consists of a metal case comprising the plate IO0I and a cover plate I002 secured thereto. As shown in Figures 3 and 8, th cover plate extends over a portion of the plate ItOI. Means for storing the total is disposed between the plate IO0I and the cover plate I002 and consists of a plurality of rows of identical slides I003, only one of which will be described. The slide has rectangular top and bottom parts I004 and I005 (Figs. 2 and 3) .interconnected by side portions I006. The sides 200 are disposed in slots I001 in the plate IO0I. As shown in Figure 8, the slots I001 are of greater length than the length of the slid I003 so that the slide is capable of movement from one end of the slots to the other. As will presently appear, when disposed in the forward ends of the slot, the slide does not represent a value. However, when disposed in the rear ends of the slot, as shown by the position of the slide I008, the slide does represent a value and this particular slide would represent a figure 8 in the second order. As shown in Figure 11, bearing in mind that this is the under side of the storing device, the slides are shown as adjusted to represent the total figure 2123456789.

Means are provided as will presently be described for locking the slides in their adjusted ositions, for clearing all the slides to zero, and for adjusting the slides to a new balance.

Mounted on the under side of the plate IO0I (Fig. 11) is a plate I009 for printing the name and address of the depositor and, for filing purposes, the same name and address appears on a card IOI0 (Fig. 8) attached to the top of the storing device.

AUTOMATIC PICK UP OF OLD BALANCE As shown in Figure 7, the machine of the patent has mounted on the rear end thereof a case Hill which is insulated therefrom by means of blocks of insulation IOI2. The paper tapes I058, after they leave the platen 65, pass through the case IOII by way of guides IOI3. The case has a lid IOI4 connected thereto by means of hinges IOI5.

In operation the operator picks up the storing device I000 belonging to the account which is to be posted and places said storing device in the top of the case IOII (Fig. 9) which is provided with a ledge I0 I 6 (Figs. 9 and 12) on which the device rests, and a rim Hill for locating the device in position. The operator then closes the lid IOI4 which has a portion iIli8 (Fig. 9) which is adapted to engage the edge of the cover I002 of the storing device I000 to move it to the left in Figure 9 against the rim MIT. The lid IOI4 is then latched down to resiliently hold the stori-ng device I 000 on its seat I0! 5. For this purpose a latch comprising a yoke I 0I0. (Figs. 9 and 10), pivoted at I020 in brackets on the case I0! I, has a yoke I02I which is pivoted thereto at I022. A hook I023 is resiliently mounted in the yoke I02I by means of a spring I024 and is adapted to be engaged with a pin I025 on the lid IOI4.

To facilitate removal of the storing device I000 from the case IOII at the conclusion of the posting operation after the lid IOI4 ha been raised, there are mounted in the case two spring-pressed ejector pins I020, I021 (Fig. 12) which are shown in detail in Figures 17 and 18. The pins are identical and only one will be described in detail. Pin I026 is slidably mounted in a bracket I020 and is urged upwardly by the spring I020. The ejector pin I926 operates a switch for a purpose later described. When the storing device I000 is placed in the case I0! I and the lid closed, the pins I020, I027 are depressed. The pin I020 rocks a lever I030 (Fig. 18) counterclockwise on its pivot and, by means of a pawl I03I, momentarily closes the switch I032. When the lid is opened the pins I026, I021 move upwardly to lift the device I000 to facilitate removal thereof from the case. When the pin I026 moves upwardly, the lever I030 is moved clockwise by a spring I033 and the pawl I03I wipes past the switch I 032 without operating it.

Supported within the case IOII are a plurality of parallel longitudinal bars of insulation I034 (Figs. 12 and i l). Each bar has mounted therein nine spring-pressed ball contacts I035. The construction of one of these contacts is shown in detail in Figure 14. Each of the slides I003 (Figs. 11 and i l) has formed thereon a protuberance I 030, which, in the cleared position of the slide, is out of engagement with the associated ball contact I035 when the device is in the case.

However, as shown at I031, each slide which has been set to active position to indicate a number is so positioned that its protuberance I036 contacts the associated ball I035. The contacts I035 (Fig. 12) are connected by separate wires to olenoids for pulling down the keys I2I in the keyboard of the machine. As shown in Figure 5, each of the keys I2I has a solenoid I038 for operating it. It will be understood that each key in the keyboard is provided with such a solenoid and that each of these solenoids is connected to the corresponding contact I035. The detailed construction of one of the solenoids I030 is shown in Figure 4. The solenoid I030 has a cylindrical steel core I039 which has connected thereto the steam I040 of the key, which stem is made of non-magnetic material, and the portion I04I of the key stem having the stop pin I22 therein is secured to the lower end of the core I039 and is also made of non-magnetic mtaerial.

A coil spring I002 (Fig. 5) bearing against pins I043 in the frame of the machine and against pins I044 on thekey stems serves to elevate depressed keys when they are released. It is to be understood that a depressed key i held down by the latch mechanism provided in the machine of thepatent.

Referring now to the wiring diagram (Fig. 26), it will be seen that when the storing device I000 is secured in place in the case I0! I, the protuberance I036 of a slide I003 which has been set to active position will make contact with its associated ball contact I035 which is connected by'a wire I045 to the associated solenoid I038 so that if, for example, the No. 1 slide in the first order is set to active position, it will be con nected to the No. 1 solenoid in the first order of the machine. The case Hill is connected in any suitable manner to one side of the electric power supply so that, asdiagrammatically illustrated in Figure 26, all the slides I003 are connected by a line I040 to a line I04! that is connected to the power line I040.

It will be recalled that when the lid is closed, the arm I030 (Fig. 26) by means of its pawl I03I momentarily closes the switch I032. One side of the switch I032 is connected by lines I049, I050 to power line I040. The other side of switch I032 is connected by line 05I to a solenoid I052- which is connected by a line I053 to the power line I054. The solenoid I052 moves the plunger I055 into engagement with a spring contact I056 thereby completing a circuit from the line I053 to the line I05! to which each of the solenoids I038 is connected.

The switch I 032 is momentarily closed to energize the solenoid I052 in order to close the switch I055, I056 which remains closed until the plunger I055 is withdrawn from engagement with the spring contact I056. It will be understood that in Figure 26 only one row of key-operating solenoids I030 and their associated contacts I035 have been shown but that in the actual machine there will be similar rows of solenoids and contacts for each row of keys in the machine. Thus in any order where a slide I003 has been set to active position, the circuit is completed which causes energization of the associated solenoid I038 which operates to pull down the corresponding key in the keyboard which, as explained be-. fore, is held down by its latch mechanism. In this way an old balance stored in the storing device IOIl0 is transferred to the keyboard of the accounting machine, and this is accomplished automatically merely by placing the storing device I000' in the case I OH and closing the lid IOI4.

It will be recalled that in the machine of the patent, after the operator has set up the old balance in the keyboard, he depresses the sub-total key 392v (Fig. 1) and the motor bar 66. This he now proceeds to do and upon depression of the sub-total key 332 (Fig. 13), the switch I059 is closed. As shown in Figure 26 one side of this switch is connected by a line I000. to the power line I 003, and the other side is connected to a line IO0I. Line I062 connected to the line IOBI. is connected to a solenoid I053 which is connected by a line I004 to the power line I054. When energized, the solenoid I063 withdraws the plunger I055 from engagement with the contact I 056 thereby opening the circuits of the key-operating solenoids I038.

PRINTING NAME AND ADDRESS A line I005 connected to the line I06I is connected to a printing solenoid I006 which is connected to a line I067 connected to the power line I054 so that, upon depression of the sub-total key, the printing solenoid I006 is energized. This is utilized to print the name and address as will now be explained. It will be recalled that the storing device I000 (Fig. 11) has a plate I000 on which the name and address of the depositor is embossed. When the storing device I000 is placed in the case I,0II (Figs. 7 and 12), the name and address plate I009 is disposed above a ribbon I068. The details of the printing mechanism are shown in Figures 17 and 19. The ribbon I008 is wound on a spool I069 which can be mounted for rotation in brackets I010 by Opening the hinged cover I01I. The ribbon I068 passes over supporting rollers I012, I013, I014, I015 to a winding spool I016.

The impression of the plate I009 is made by a hammer I011, rectangular in form, secured to a plunger I018 of non-magnetic metal attached to a core I019 in the solenoid I066. Suitable guides I080 are provided for the hammer I011. Upon energization of the solenoid I066, the hammer I011 is moved upwardly to impress the name and address on the paper strip III-58 as shown at H90 (Fig. 22) and When the solenoid I066 is de-energized, a spring I08I restores the hammer to the position shown.

Downward movement of the hammer actuates the ribbon feed mechanism. The slide I082 has an ear I083 underlying the hammer I911 and has a pin I084 engaging the end of a lever I085 which is urged clockwise (Fig. 19) on its pivot by a spring I086. The pawl I081 mounted on the arm I085 actuates a ratchet wheel I088 to wind the spool I010. In this way the name and address is printed on the tape when the sub-total key is depressed.

Clearing the storing device The slides I003 in the storing device I000 are normally locked, and the locking mechanism will now be described. Each of the slides I003 (Figs.

I089 to hold the slide I003 in one end or the other I r of its slot. As shown in Figure 8, a lug I090 by engaging the pin I089 on the slide I008 is holding the slide in the rear end of the slot, that is, in its active position whereas the slide I09I adjacent thereto is locked in the forward end of its slot, that is, in the inactive position. The locking lugs I090 are formed as part of two locking plates I092, I093 which are mounted on the under side of the cover I002 by pin and slot connections I094 so that, as viewed in Figure 8, the locking plate I092 may be moved to the left and the locking plate I093 may be moved to the right. When this occurs all of the locking lugs I090 are moved laterally out of engagement with their associated pins I089 thereby unlocking all of the slides I003.

Normally the parts occupy the position shown in Figure 8 by reason of the fact that the two locking plates I002, I093 are drawn together by two springs, one of which is shown at I095. The plates I092, I003 abut each other at their forward and rear ends. The abutting portions at the rear end are shown in Figure 8 at I096 and I091. Complementary apertures in these two abutting portions form a square aperture I098.

When the storing device I000 is seated in the case I0! I, the apertures I098 are disposed immediately above the bevelled ends I099 (Figs. 12 and 20) of slides H00 which are adapted to be projected upwardly through apertures I IOI (Fig. 11) to enter the apertures I030 (Fig. 8) and cam the locking plates I992, I093 apart to release the slides I003. The detailed construction of one of the slides H00 is shown in Figure 20. The slide has two notches H02, H03 with which a spring-pressed ball H04 cooperates to hold the slide in either its up or down position and the slide is connected to the collar H05 of a plunger I I06 of non-magnetic material which is connected to the core H01 of a double solenoid. The solenoid H00 serves to move the slide H00 upwardly and the solenoid H09 moves it downwardly. It should be borne in mind that when the slides H00 are projected upwardly, the slides I003 in the storing device are unlocked and when the slides I I00 are moved downwardly, the slides I003 are locked in their adjusted position. Referring to Figure 26 the line I06I which is connected to one side of the sub-total key switch I059 has connected thereto a line I I I0 connected to one of the solenoids H08 which is connected by a line IIII to the line I061. The line IIIO has connected thereto a line II l2 which i connected to the other solenoid H08 which is connected by a line I I I3 to the line I061. Thus upon depression of the sub-total key, both solenoids I I08 are energized to move the slides I I00 upwardly to unlock the slides I003 in the storing device.

After the slides I003 are unlocked they are to be cleared, that is, any slide which is set to active position is now to be set to inactive position. For this purpose one of the slides H00 (Fig. 20) has two insulated pins IH I which operate a doublethrow switch having a common contact arm I I I5 engaged by the pins HM. In the down position of the slide I I00, shown in Figure 20, switch HIS is closed and switch III1 is open. When as just described the slide H00 is moved upwardly, the switch III1 is closed and the switch III6 is opened. These parts are shown in Figure 26 where it will be seen that the common contact arm HI5 is connected by a line IH8 to the line I051, and the other side of the switch III1 is connected by a line III9 to the solenoid H20 which operates the clearing mechanism, the operation of which will presently be described. This solenoid is also connected to the line I06I. Therefore, upon depression of the sub-total key 392, the solenoid I I20 is energized after the switch I I I1 is closed.

The solenoid H20 is shown in Figure 21 where it is mounted in the case IOI I and has a springreturned plunger II2I connected to a crank H22 secured to a shaft H23 having an arm H24 secured thereto. There are a plurality of shafts similar to the shaft H23, and bearing the same reference numerals, which are mounted in the case and are arranged parallel and transversely thereof (see Figure 12). Each of these shafts has an arm H20 secured thereto, and the arms H24 are interconnected for simultaneous movement by a link H25. A stop H26 (Fig. 21) cooperates with a lug I I21 on one of the arms I I24 to limit clockwise rotation of the shafts I I23. When the solenoid H20 is energized, the shafts are rotated counterclockwise. On each of the shafts H23 a series of setting arms H28 are mounted, there being one of these arms in each order. As shown in Figure 14, the shafts I I23 are splined and each arm H28 has a tooth or key H29 engaging therein. The width of the spline exceeds the width of the key for a purpose hereinafter described. As previously described after the slides I003 (Fig. 15) have been unlocked, the clearing mechanism operates to rotate the shafts H23 counterclockwise (Fig. 15) moving each arm H28 to the broken-line position, thereby moving the associated slide I003 from its active position shown in full lines to its inactive position shown in broken lines. It will be understood that due to the simultaneous operation of all the shafts H23 and the levers H28 mounted thereon, any slides I003 set in the active position will be moved to the inactive position thereby clearing the total or old balance out of the storing device. The

storing device is now conditioned to. receive the new balance.

TRANSFER OF NEW BALANCE TO STORING DEVICE As already stated, the operator proceeds to post the checks and deposits in the usual manner and then depresses the balance key 292 (Fig. 1) and the motor bar 66 in order to print the new balance. I have provided mechanism which enables the operator to transfer the new balance to the storing device before printing the balance. For this purpose I have provided a new balance key H which, as shown inFigure 24-, is suitably sup-- ported for vertical sliding movement in brackets on the exterior of the machine and has a spring I I3I for restoring the key. Upon depression of the key H30, a pin I I32 thereon acting on the cam face I I33 of a pawl II 34 pivoted to a slide H35 "causes the slide to be moved rearwardly.

The rear end of the slide is connected to a crank arm I I36 secured to a shaft I I31 which is thereby rocked counterclockwise, or clockwise as viewed in Figure 23. Within the left side of the case of the machine, the shaft H31 has secured thereto a latch H38 urged counterclockwise by spring H35. lhe latch H38 engages an ear H40 on an arm HAI secured to a shaft H02 which extends transversely of the machine and is suitably supported by insulated bearings in the sides thereof. The shaft Hi2 has a pinion I I43 made of nonconducting material engaging agear H M which has a pin H45 engaging a slot I I46 in a plunger H41 connected to the core of a solenoid H 1 8. The plunger H41 has a washer H49 between which and the solenoid is compressed a spring H50 so that upon release of the arm IMI bythe latch II 38, the spring H50 moves the plunger H41 to the left rotating the gear H44 clockwise and the pinion H43 counterclockwise. The arm H 3!v is one arm of a transversely extending bail I I5I which is thereby mounted for rotation with the shaft II 42. It will thus be seen that upon release of the latch II 38,. the bail I I5I will rotate counterclockwise.

Referring now to Figure 6, in each order of the machine there is arranged a series of nine contacts I I52 suitably mounted on a segment of insulation I I53, and cooperating with each series of contacts II 52 is a brush H5 3 carried by an arm I I rotatably mounted on the shaft H42 so that upon counterclockwise movement of the bail H5I, the brush arms H55 are free to rotate counterclockwise. The movement of each of these brush arms is controlled by the position of the totalizer gear I08 in the No. 1 totalizer as will now be described.

Each brush arm H55 has secured thereto a pinion H56 connected by an idler H51 made of non-conducting material to a gear H58 which meshes with a rack I I59 having a sensing finger H50 integral therewith. A spring HBI urges the finger I I into contact with a stepped cam I I52 which is secured for rotation with the adjacent totalizer gear I08. The spring II 6! also causes the brush arm H55 to follow the bail H5I until movement of the finger H50 is stopped by engagement with a step of the cam II 02. When this occurs the brush H54 is in contact with the contact H52 corresponding to the number at which the totalizer gear stands.

Each of the contacts I I52 in each order is connected to the corresponding solenoid H53 (Fig. 14) in the case IOI I, there being a solenoid for each of the arms H28 as shown in Figure 12.

.ciated slide I503 to active position.

Referring to Figure 14 it will be noted that the core of the solenoid I I63 is connected to a springurged plunger H54 connected to an arm H55 of the lever H28. When one of the solenoids H63 is energized, it rocks the arm I I23 clockwise from the broken line position shown in Figure 14 to the full line position thereby setting the asso- The solenoids are not energized, however, until the bail 5 ISI reaches the end of its. upward movement so that the contacts H52 (Fig. 6) are dead during the time that the brushes H54 are moving over them.

After all of the brush arms I I55 have been set, continued movement of the bail I E 5i and its arm Hit (Fig. 23) brings a brush H55 on the arm H ll into contact with the contact II 61. Now referring to'the wiring diagram (Fig. 26), it will be seen that when the brush I :56 engages the contact II 51, a circuit is completed from the power line I048 through the line I N58 to the contact H51 through the brush H65, the arm H4I, the shaft H422 to the brush arms H55 (only one of which is shown in Figure 26) hence completing a circuit through the contact H52 on which the brush H 54 is resting through the connecting line H59 to the appropriate solenoid H53 which is connected to a common line I I10 connected to the power line I054. In this Way the selected solenoids H63 are energized to rock their asso ciated setting arms H28 to set the new balance in the storing device. While the arms are still in their setting position shown in Figure 14, the final movement of the bail I I5I (Fig. 23) brings the brush II1I into contact with a contact H12, a stop H13 limiting upward movement of the ball. The contact H12 (see Figure 26) is connected by a line H14 to the solenoids I I09 which serve to withdraw the slides H00 to cause locking of the adjusted slides in the storing device. Upon downward movement of the slide H53 which operates the switch arm II i5, switch II I1 is opened and the switch I H6 is closed. This switch is connected by a line H16 to a solenoid g l I 38 which is connected through a switch I I 18 to a line H15 connected to the line I043. The switch E I18 (Fig. 23) is normally held open by the core H of the solenoid Hts. As soon as the bail H5! is unlatched, this switch closes so that when the brush II'II engages the contact I12, the solenoid H48 is energized to restore the bail I I 5I by moving the plunger I I41 to the right and through the gears II 13, II 44 rotating the shaft H 42 clockwise. At the end of the downward travel, which is limited by a stop I Hit, the latch I I38 engages the ear I I40 on the arm I MI and at the same time, the core H 80 opens the switch Hi0 thereby (is-energizing the solenoid H48. This occurs even though the new balance key I I30 (Fig. 24) has not been released by the operator because the pin I 132' passes beyond the pawl H3 in its downward movement and the slide H35, after causing unlatching of the bail, returns immediately to the right. When the operator releases the key H30, the pin H32 rocks t pawlv I I 3 3 without actuating slide H35.

OPERATION Otd balance pickup When it is desired to post a certain account. the operator selects from a suitably indexed file the storing device I000 (Fig. 8) for that account. places the storing device in case IiiI I (Fig. 7 and closes lid IIJI4, which operation causes the storing device to, depress pins I025 and IE2! (Fig. 12).

11 Depression of pin I026 (Fig. 18) causes momentary closure of switch 1032, thereby energizing solenoid I052 (Fig. 26) which closes master switch I055-I056.

When the storing device is located in the case, as described above, slides I003 (Fig. 11) which are in operative position, that is, those slides indieating a value, are in cooperative engagement with correspondin spring-pressed balls I235 (Fig. 12), thereby energizing associated solenoids I038 (Fig. 26) causing keys 52I (Fig. 5) associated therewith to be depressed. Thus the value stored in the device is transferred to the machine.

The operator then depresses sub-total ke 392 (Fig. 13) which closes switch I059 (Fig. 26) causing energization of solenoid I063 to open master switch I055-I056, thereby de-energizing solenoids I038. Depression of sub-total key 392 also energizes solenoid print hammer I011 causing the name and address on plate I009 secured to the storing device to be printed on tape I958 as shown at H90 in Figure 22.

Depression of key 392 (Fig. 26) and closing of switch I059 also closes the circuits to solenoids H08 raising the slides I I09 to unlock the storing device as previously described.

Immediately after storing device I000 is unlocked, the storing device clearing mechanism is operated in the following manner. Upward movement of pin H (Fig. 26) urges leaf Hi into contact with switch member I I I1, energizing olenoid H20 (Fig. 21) to actuate arms H28 thereby restoring slides I003 (Fig. 11) to inactive position.

From the foregoing it will be understood that insertion of the storing device in the machine and depression of the sub-total key 392 causes the value originally held in the storing device to be transferred to the keyboard of the machine, the name and address to be printed on the tape, and the old balance to be cleared from the storing de vice.

The operator then depresses the motor bar 66 (Fig. 1) which causes the Old balance set in the keyboard to be printed on tape i058, as shown at II9I in Figure 22, and to be stored in the No. 1 totalizer in the conventional manner as fully described in the above-cited Christian patent.

The operator then proceeds to post checks and deposits in the usual manner and, as described in the Christian patent, the items are printed on the tape as shown at I I92 (Fig. 22).

New balance pick-up At the conclusion of such posting as is necessary, depression of the New balance key H30 (Fig. 24) causes latch H38 (Fig. 23) to release arm II4I, allowing associated bail H5i to rotate counterclockwise. As arm IE4! rotates as described above, the core I I80 of solenoid I I48 (Fig. 23) moves laterally closing switch H18 on one lead to solenoid H48. The above-mentioned displacement of bail IIEI allows arms H55 (Fig. 6) to rotate counterclockwise. Each arm H55 rotates until its associated finger H50 engages its stepped cam I I02, thereby adjusting the brushes H55 in accordance with the value in the No. 1 totalizer. When arm IMI (Fig. 26) with contacts H68 and II'iI secured thereto, rotates so that contacts H65 and i I67 are in engagement, a circuit is closed energizing those solenoids I I63 which are electrically connected to the above-mentioned brushes H54, positioning the slides i003 (Fig. 14) associated therewith to active or registering po I056 (Fig. 17) which raises 12 sition. In this way the value standing in the No. 1 totalizer is set in the storing device.

At the end of rotation of arm II4I (Fig. 23), while contacts H66 and H61 are still in engagement, contact II'II secured to arm H II engages contact H12, closing another circuit, energizing solenoids H09 (Fig. 26) to withdraw slides H00, thereby causing slides I003 in storin device I000 to be locked in their adjusted positions. Withdrawal of slide H00 connected to leaf III5 (Fig. 26) closes the circuit to solenoid H48 which restores bail H5! (Fig. 23) to its original position.

From the foregoing it will be seen that depression of the New balance ke I I30 will cause the value in the No. 1 totalizer to be transferred therefrom to the storing device and to be locked therein. At the conclusion of this operation, the operator depresses balance key 292 (Fig. l) and motor bar 68, and the machine disclosed in the above-mentioned Christian patent prints the New balance on tape I058 as shown at H93 in Figure 22.

After posting the account the operator removes the storing device I000, and the storing device for the next account is placed in the case IN I.
